Aerodynamic modifications to save gasoline

Hi,

I have a long thread, with lots of pictures of the aerodynamic mods that I have done to my Scion xA, over at EcoModder.com


The grill block and the fog light covers were the best improvements = +10% or so improvement in overall fuel economy.

The smooth wheel covers helped ~6% or so.

The rear wheel skirts, and the Kamm back helped some, too.

I'm still keeping above 41mpg even during the winter cold and ice and snow.  Before I started ecodriving, my best MPG on a tankful was 42.5, so getting just shy of this for my worst tankful during a New England winter, is a good thing; if I say so myself!
